Young (younger than me, and I am only 26 years old!) Swiss composer, who's specialization are fairy twomovers with complicated letter themes. Judge of our 3rd TT introduced himself with 5 his selected compositions with his own short remarks.

1.Sg6! th. 2.Se5#,
1...NEbb4 a 2.VAe3# B Theme A & Theme B & Ekström's line combination
1...NEfb4 b 2.VAf3# A Theme A & Theme B & Ekström's line combination

1.Sc6 ! th. 2.Se5#,
1...NEbb4 a 2.VAf3# A Theme A & Theme B & Bruch's line combination
1...NEfb4 b 2.VAe3# B Theme A & Theme B & Bruch's line combination

Very complicated reciprocal change of mates. In both solutions one can find Isajev line combinations and in first and second solution there are Ekström's and Bruch's line combinations respectively.

Here you can see black correction of 6th degree without any flaws. French friends made construction much better than I did. So it is really super now!

Prototype of such complex of changes in 4 phases and 4 variations, 2 reciprocal changes between any 2 phases of them. Duel of 3 knights - they make all thematical moves. Moves by black knight are defences, as he can change colour of white queen as an answer to threat check.
